Murata Electronics' ECAS (90) series 330 µF (7343/D4 case size) polymer aluminum electrolytic capacitors realize low ESR, low impedance, and high capacitance by means of multilayer aluminum foil for anode and solid body polymer for cathode. With no bias characteristics and stable temperature characteristics, the ECAS series have excellent performance in ripple absorption, smoothing, and transient response suitable for numerous applications. Therefore, the ECAS series is suitable for the input/output of various power supply circuits and the backup use of the CPU circumference.
